Abstract

This procedure includes the following steps: - a partitioning of all the carrier frequencies constituting the frequency resource available for this network into batches of unequal magnitude, - an allotment to every site of the network, at the time it enters the network, manifested by a request for frequency allocation for connection between this site and another site, termed the site of first link-up for the relevant site, and, prior to this allocation, of one state out of two possible complementary states, this state being chosen so as to obtain complementary states for the relevant site and for its site of first link-up, and being retained for subsequent connections between the relevant site and other sites of the network, - for every connection to be established between two sites of this network, a frequency allocation by random drawing from that one of these batches which is of greatest magnitude, if the relevant sites are in complementary states, or from that one of these batches which is of lesser magnitude if the relevant sites are in identical states. <IMAGE>

Description

La présente invention concerne un procédé d'allocation de fréquences porteuses pour transmission à l'intérieur d'un réseau de transmission.The present invention relates to a method for allocating carrier frequencies for transmission within a transmission network.

L'invention s'applique notamment aux réseaux de transmission tactiques par faisceaux hertziens, pour lesquels une telle allocation est rendue particulièrement complexe du fait de l'extrême mobilité de ces réseaux.The invention applies in particular to tactical radio-relay systems, for which such an allocation is made particularly complex due to the extreme mobility of these networks.

D'une manière générale, pour de tels réseaux, une telle allocation doit avoir un caractère aléatoire de façon à décourager toute tentative de prévision par l'ennemi. Il est ainsi connu de réaliser, pour toute fréquence à allouer à une liaison entre un équipement d'émission situé dans l'un des sites de ce réseau et un équipement de réception situé dans un autre site de ce réseau, une telle allocation par tirage aléatoire dans l'ensemble des fréquences porteuses constituant la ressource en fréquences disponible pour ce réseau, après avoir retiré de cet ensemble les fréquences dites interdites pour la liaison considérée, du fait de contraintes internes à ce réseau dues à la proximité d'autres équipements d'émission ou de réception, dans les sites considérés ainsi que dans des sites voisins.In general, for such networks, such an allocation must be random in order to discourage any attempt at forecasting by the enemy. It is thus known to carry out, for any frequency to be allocated to a link between a transmission equipment located in one of the sites of this network and a reception equipment located in another site of this network, such allocation by drawing random in the set of carrier frequencies constituting the frequency resource available for this network, after having removed from this set the so-called prohibited frequencies for the link in question, due to internal constraints in this network due to the proximity of other equipment d 'transmission or reception, in the sites considered as well as in neighboring sites.

Un tel procédé a pour inconvénient essentiel de conduire en pratique à des situations dites de blocage, où des demandes d'allocation ne peuvent aboutir.The essential drawback of such a method is that it leads in practice to so-called deadlock situations, where allocation requests cannot succeed.

La présente invention a pour but d'éviter un tel inconvénient.The object of the present invention is to avoid such a drawback.

La présente invention a pour objet un procédé d'allocation de fréquences porteuses pour transmission à l'intérieur d'un réseau de transmission, notamment tactique, essentiellement caractérisé en ce qu'il comporte :

  • un découpage de l'ensemble des fréquences porteuses constituant la ressource en fréquences disponibles pour ce réseau, en lots d'importance inégale,
  • une attribution à tout site du réseau, au moment de son entrée dans le réseau, se traduisant par une demande d'allocation de fréquence pour une liaison entre ce site et un autre site, dit site de première mise en relation pour le site considéré, et préalablement à cette allocation, d'un état parmi deux états complémentaires possibles, cet état étant choisi de façon à obtenir des états complémentaires pour le site considéré et pour son site de première mise en relation, et étant conservé pour des liaisons ultérieures entre le site considéré et d'autres sites du réseau,
  • pour toute liaison à établir entre deux sites de ce réseau, une allocation de fréquence par tirage aléatoire dans celui de ces lots qui est de plus grande importance, si les sites considérés sont dans des états complémentaires, ou dans celui de ces lots qui est de moindre importance si les sites considérés sont dans des états identiques.
The subject of the present invention is a method of allocating carrier frequencies for transmission within a transmission network, in particular a tactical one, essentially characterized in that it comprises:
  • a division of all the carrier frequencies constituting the frequency resource available for this network, into lots of unequal importance,
  • an assignment to any site in the network, upon entry in the network, resulting in a request for frequency allocation for a link between this site and another site, known as the first connection site for the site in question, and prior to this allocation, from one of two states complementary possible, this state being chosen so as to obtain complementary states for the site considered and for its site of first connection, and being kept for subsequent links between the site considered and other sites of the network,
  • for any link to be established between two sites in this network, a frequency allocation by random draw in that of these lots which is of greatest importance, if the sites considered are in complementary states, or in that of these lots which is less important if the sites considered are in identical states.

D'autres objets et caractéristiques de la présente invention apparaîtront à la lecture de la description suivante d'un exemple de réalisation, faite en relation avec les dessins ci-annexés dans lesquels :

  • la figure 1 est un diagramme destiné à illustrer l'étape du procédé suivant l'invention, suivant laquelle est effectué un découpage de la ressource en fréquences disponible pour le réseau considéré, en lots d'importance inégale;
  • la figure 2 est un diagramme destiné à illustrer l'étape du procédé suivant l'invention, suivant laquelle est effectué une attribution d'un état parmi deux états complémentaires à tout site de ce réseau,
  • la figure 3 est un diagramme destiné à illustrer les contraintes internes au réseau, conduisant à la définition de fréquences dites interdites.
Other objects and characteristics of the present invention will appear on reading the following description of an exemplary embodiment, made in connection with the attached drawings in which:
  • FIG. 1 is a diagram intended to illustrate the step of the method according to the invention, according to which a division of the frequency resource available for the network considered is carried out, into batches of unequal importance;
  • FIG. 2 is a diagram intended to illustrate the step of the method according to the invention, according to which an allocation is made from one of two complementary states to any site of this network,
  • FIG. 3 is a diagram intended to illustrate the internal constraints in the network, leading to the definition of so-called prohibited frequencies.

Le diagramme de la figure 1 représente un exemple de ressource en fréquences disponible pour un réseau de transmission, cette ressource en fréquences étant en l'occurence formée de blocs disjoints sur l'axe des fréquences, tel qu'illustré schématiquement à la première ligne de ce diagramme où de tels blocs, à titre d'exemple de largeur inégale et en nombre égal à six, sont repérés respectivement B1, B2, B3, B4, B5, B6.The diagram in FIG. 1 represents an example of a frequency resource available for a transmission network, this frequency resource being in this case formed by disjoint blocks on the frequency axis, as illustrated diagrammatically in the first line of this diagram where such blocks, by way of example of unequal width and in number equal to six, are identified respectively B1, B2, B3, B4, B5, B6.

La deuxième ligne de ce diagramme illustre un exemple de répartition des fréquences de cette ressource en trois lots d'inégale importance, repérés respectivement A, B et C par ordre d'importance décroissante.The second line of this diagram illustrates an example of the distribution of the frequencies of this resource in three batches of unequal importance, identified respectively A, B and C in order of decreasing importance.

A titre d'exemple, le lot A pourra constituer 60 % de la ressource disponible, le lot B, 30 % et le lot C, 10 %. D'autres exemples de répartition sont bien entendu possibles.For example, lot A could constitute 60% of the available resource, lot B, 30% and lot C, 10%. Other examples of distribution are of course possible.

Dans l'exemple illustré sur la figure 1, le lot A est formé à partir des blocs B1 et B2 et d'une partie du bloc B3, le lot B est formé à partir de l'autre partie du bloc B3, des blocs B4 et B5, et d'une partie du bloc B6, et le lot C est constitué de l'autre partie du bloc B6. D'autres exemples de répartition sont bien entendu possibles.In the example illustrated in FIG. 1, batch A is formed from blocks B1 and B2 and from part of block B3, batch B is formed from the other part of block B3, blocks B4 and B5, and part of block B6, and lot C consists of the other part of block B6. Other examples of distribution are of course possible.

La figure 2 représente schématiquement un réseau de transmission maillé, dans lequel les noeuds de ce réseau sont symbolisés par des cercles, les usagers de ce réseau sont symbolisés par des triangles, et les numéros associés à chaque liaison usager-noeud ou noeud-noeud représentent le numéro d'ouverture de cette liaison au fur et à mesure du déploiement de ce réseau, c'est-à-dire de l'entrée de ces noeuds ou de ces usagers dans ce réseau.FIG. 2 schematically represents a mesh transmission network, in which the nodes of this network are symbolized by circles, the users of this network are symbolized by triangles, and the numbers associated with each user-node or node-node link represent the opening number of this link as and when this network is deployed, that is to say when these nodes or these users enter this network.

Ces cercles ou ces triangles (qui seront regroupés sous le terme générique de sites) sont, à des fins d'illustration du procédé suivant l'invention, coloriés tantôt en noir, tantôt en blanc, de la façon maintenant décrite.These circles or these triangles (which will be grouped under the generic term of sites) are, for purposes of illustration of the process according to the invention, colored sometimes in black, sometimes in white, in the manner now described.

Tout site pour lequel aucune liaison n'a encore été établie se voit, au moment de son entrée dans le réseau, c'est-à-dire au moment d'une demande d'allocation de fréquence pour une liaison entre lui-même et un autre site, dit site de première mise en relation pour le site considéré, et préalablement à cette allocation :

  • soit colorié arbitrairement (en noir ou en blanc), si cet autre site n'est pas lui-même déjà colorié, cet autre site se voyant alors lui-même colorié de façon opposée,
  • soit colorié de façon opposée à cet autre site si celui-ci était lui-même déjà colorié.
Any site for which a connection has not yet been established is seen, at the time of its entry into the network, that is to say at the time of a request for frequency allocation for a link between itself and another site, known as the first link site for the site in question, and prior to this allocation:
  • either arbitrarily colored (in black or white), if this other site is not itself already colored, this other site then seeing itself colored in opposite fashion,
  • be colored opposite to this other site if it was itself already colored.

Ainsi comme illustré sur cette figure, lors du déploiement du réseau, les différents sites sont coloriés de proche en proche de deux couleurs alternées, définissant ainsi un ensemble de liaisons aux couleurs alternées ("blanc-noir" ou "noir-blanc").Thus, as illustrated in this figure, during the deployment of the network, the different sites are colored step by step with two alternating colors, thus defining a set of links with alternating colors ("white-black" or "black-white").

Pour des liaisons de ce type, l'allocation d'une fréquence sera réalisée par tirage aléatoire dans le lot A de plus grande importance.For links of this type, the allocation of a frequency will be carried out by random drawing in lot A of greater importance.

Un site colorié de la façon indiquée ci-dessus conserve en outre la couleur ainsi acquise pour d'éventuelles liaisons ultérieures entre lui-même et des sites autres que ce site de première mise en relation. Dans ces conditions, il est possible que l'on soit amené, au fur et à mesure du déploiement du réseau, à effectuer des liaisons entre sites déjà coloriés, et ce de façon identique.A site colored in the manner indicated above also retains the color thus acquired for possible subsequent links between itself and sites other than this site of first connection. Under these conditions, it is possible that, as the network is deployed, to make connections between already colored sites, and this in an identical manner.

Pour ces liaisons, du type "blanc-blanc" ou "noir-noir", statistiquement en nombre plus restreint que les précédentes, l'allocation d'une fréquence sera effectuée par tirage aléatoire dans le lot B de moindre importance.For these links, of the "white-white" or "black-black" type, statistically in a smaller number than the previous ones, the allocation of a frequency will be made by random drawing in lot B of lesser importance.

Le caractère aléatoire du tirage des fréquences est ainsi tempéré par un classement initial déterministe de ces fréquences. Le caractère semi-aléatoire ainsi obtenu permet de faire face aux situations de blocage mentionnées plus haut.The random nature of the frequency selection is thus tempered by an initial deterministic classification of these frequencies. The semi-random nature thus obtained makes it possible to deal with the blocking situations mentioned above.

La constitution d'un lot de fréquences en réserve (lot C) permet éventuellement d'attribuer, en dernier recours, un couple de fréquences à une liaison pour laquelle une fréquence n'aurait pu être allouée.The constitution of a set of frequencies in reserve (lot C) eventually makes it possible to allocate, as a last resort, a couple of frequencies to a link for which a frequency could not have been allocated.

Le tirage aléatoire du couple de fréquences nécessaires à la liaison ainsi coloriée, dans le lot correspondant audit coloriage, est réalisé après avoir retiré de ce lot les fréquences dites interdites.The random selection of the couple of frequencies necessary for the link thus colored, in the batch corresponding to said coloring, is carried out after having removed from this batch the so-called prohibited frequencies.

Les différentes sources d'interdiction de fréquences sont rappelées sur le diagramme de la figure 3.The different sources of frequency prohibition are recalled in the diagram in Figure 3.

Cette figure représente schématiquement des équipements d'émission, notés E, et des équipements de réception, notés R, de trois sites voisins, notés S1, S2, S3.This figure schematically represents equipment transmission, denoted E, and reception equipment, denoted R, from three neighboring sites, denoted S1, S2, S3.

Pour une liaison à établir, à titre d'exemple entre un émetteur du site S1 et un récepteur du site S2, peuvent être considérées comme fréquences interdites, après vérifications :

  • une fréquence allouée à l'émetteur associé au récepteur considéré du site S2,
  • une fréquence allouée à un émetteur du site S2 autre que celui associé au récepteur considéré,
  • une fréquence allouée à un émetteur du site S1 autre que l'émetteur considéré,
  • une fréquence allouée à un émetteur d'un site, tel que S3, autre que S1 et S2.
For a connection to be established, for example between a transmitter of site S1 and a receiver of site S2, the following frequencies may be considered prohibited, after checks:
  • a frequency allocated to the transmitter associated with the considered receiver of site S2,
  • a frequency allocated to a transmitter of site S2 other than that associated with the receiver considered,
  • a frequency allocated to a transmitter of site S1 other than the transmitter considered,
  • a frequency allocated to a transmitter of a site, such as S3, other than S1 and S2.

Sur la figure 3 est schématisée en trait plein la liaison à établir considérée, et en pointillés les interférences possibles avec les fréquences interdites.In FIG. 3 is shown diagrammatically in solid lines the connection to be established considered, and in dotted lines the possible interference with the prohibited frequencies.
